Potentiometric surface of the Aquia Aquifer in southern Maryland during the fall of 1987

January 1, 1989

A map showing the potentiometric surface of the Aquia aquifer in the Paleocene Aquia Formation in southern Maryland during the fall of 1987 was prepared by using water level measurements from 80 observation wells. The potentiometric surface was above sea level near the northeastern boundary and outcrop area of the aquifer in topographically high areas of Anne Arundel and Prince Georges Counties. The potentiometric surface was below sea level in the remainder of the study area. The hydraulic gradient was generally to the southeast toward an extensive cone of depression, which is centered around well fields near Lexington Park. Much of the cone is more than 40 ft below sea level. (USGS)
